Dear Robert,

Your questions are very interesting but I am afraid you will have difficulty
to find answers. We now very little about whales in general and anything
about reproduction is still extremely limited. For the sperm whale, we know
that most whales mate during a specific season. The length of pregnancy
lasts between ten to twelve months. A female sperm whale carries her calf
for sixteen months. My only option is to try to contact Dr. Whitehead who is
an expert in sperm whales at
Sorry and good luck,
